 I introduced the full series of fixed switches in the last thread. There are so many models in so many series. Do you get a headache distinguishing one switch from another or picking the one you need? Don't worry. You will get all your questions answered in this thread.

Question 1: Do you know how to choose a model among fixed switches? Which are Layer 2 switches? Which are Layer 3 switches?

All the S1700s are Layer 2 switches, some of which provide 100M downstream ports and some provide GE downstream ports. You can distinguish these switches from their product names. The switches with a "G" in their product names have GE downstream ports, for example, S1700-52GFR-4P-AC. The switches without "G" in their product names have 100M downstream ports.

All the S2700s are Layer 2 100M switches.

All the S3700s are Layer 3 100M switches.

The S5700-LI, S5700S-LI and S5710-LI series of the S5700s are Layer 2 GE switches (switches with "LI" in the name are Layer 2 switches), and the rest of the S5700s are Layer 3 GE switches.

The S6700s are Layer 3 10GE switches.


 

Question 2: Do you know the function of cards? Which models support cards and how to identify them?

When the fixed interfaces on the switches cannot meet the needs of users, cards of a specified type can be used. Cards are usually optional, providing more functions and applications, such as high-speed uplink interfaces and stack cards.

Series

Support for Cards

S1700

Not supported

S2700

Not supported

S3700

Only supported by the HI series

S5700

Supported by models other than the S5700-Li, S5700S-LI and S5700-26X-SI-12S-AC

S6700

Not supported

Here's a method to quickly determine whether a switch supports cards: check whether its name contains a C. For example, the S5700-28C-EI supports cards.

There are several exceptions: The S5700-24TP and S5700-48TP of the S5700-SI series do not support service cards but they support stack cards, although there is no "C" in their names.

List of cards:

Question 3: Do you know which models support PoE power supply? How many interfaces at most do they support?

Switches with PWR in the name support PoE power supply, such as the S5710-52C-PWR-EI.

PoE switches provide power for powered devices (PDs) over Ethernet electrical interfaces. All the PoE switches comply with IEEE 802.3af and 802.3at. IEEE 802.3af supports a maximum of 15.4 W power and the IEEE 802.3at supports a maximum of 30 W power. The PDs connected to a switch determine which standard the switch should comply with, and the switch is auto-sensing.

The number of interfaces that can provide PoE power supply on a switch depends on the power module used, the corresponding standard, and the switch's own limitations. Here, I'm providing the maximum number of interfaces that each series can support theoretically. See the Hardware Description of the corresponding product for details.

Series

Maximum Number of PoE Interfaces (IEEE 802.3af)

Maximum Number of PoE Interfaces (IEEE 802.3at)

S1700

Not supporting PoE

S2700

8/16/24/48

4/8/12/24

S3700

8/16/24/48

4/8/12/24

S5700

8/12/16/24/48

4/6/8/12/24/26/48

S6700

Not supporting PoE

If you want to know more about the switch product names, see the naming conventions of switches at the following website: http://forum.huawei.com/enterprise/thread-207241.html

Question 4: Do you know the software versions of switches? What is the mapping between software versions and switch models?

Huawei releases two sets of software versions for SMB switches (S1700) and non-SMB switches (S2700/3700/5700/6700). The two sets of software versions are unrelated.

The figures and tables below demonstrate switches' software version evolution and mapping between software versions and switch models.

S1700: The three software versions are independent of each other. Upgrades and downgrades cannot take place among the three versions. For example, an S1700 switch cannot upgrade from V1R6C00 to V1R7C00.

S2700/3700/5700/6700: The following table shows the mapping between software versions and switch models. The same model can be upgraded and degraded among the supported software versions.

 


Well, this is the end of today's All About Switches. Stay tuned for the subsequent series.
